Understanding and measuring factors influencing future participation is relevant to organizations. This information is useful for planning and strategic decision-making. In this work, we measure contributor characteristics and compute attrition to investigate their relationship by mining Issue Tracking System. We conduct experiments on four year data extracted from Google Chromium Issue Tracking System. Experimental results show that the likelihood of future participation increases with increase in relevance of role in project and level of participation in previous time-interval.

	abstract = {How can we understand FOSS collaboration better? Can social issues that emerge be identified and addressed as they happen? Can the community heal itself, become more transparent and inclusive, and promote diversity? We propose a technique to address these issues by quantitative analysis and temporal visualization of social dynamics in FOSS communities. We used social network analysis metrics to identify growth patterns and unhealthy dynamics; This gives the community a heads-up when they can still take action to ensure the sustainability of the project.},

	abstract = {

Every open source project needs to decide on an open source license. This decision is of high economic relevance: Just which license is the best one to help the project grow and attract a community? The most common question is: Should the project choose a restrictive (reciprocal) license or a more permissive one? As an important step towards answering this question, this paper analyses actual license choice and correlated project growth from ten years of open source projects. It provides closed analytical models and finds that around 2001 a reversal in license choice occurred from restrictive towards permissive licenses.

	abstract = {This paper provides a a framework to evaluate the transition to a OSS software solution in terms of returns and losses in the context of Public Administrations. The ultimate goal of the framework is to identify costs that are not easy to trace or that are not usually collected like user acceptance. The framework has been conducted using a Total Cost of Ownership approach, which is the most frequently used model to conduct cost comparisons between two or more IT systems. The study further implements the Goal Question Metric paradigm to identify the cost metrics. The framework relies various methods to collect the data, including questionnaires with end-users, qualitative interviews with IT-managers and company balance sheets. An example of framework{\textquoteright}s use is provided.},
